Vanda orchid plant ‘SPCDW1312’

ABSTRACT

A new and distinct  Vanda  cultivar named ‘SPCDW1312’ is disclosed, characterized by unique flower color and large flower size. The new variety is a  Vanda , typically produced as an indoor ornamental plant.

Latin name of the genus and species: Vanda hybrid.

Variety denomination: ‘SPCDW1312’.

BACKGROUND OF THE INVENTION

This application relates to a new cultivar of Vanda hybrid. The new variety is the product of a planned breeding program. The new variety originated as a seedling from the crossing of the unpatented, proprietary seed parent Vanda ‘S243P’ with the unpatented, proprietary pollen parent referred to as Vanda ‘KMK96’. The crossing was made by the inventor in his research greenhouse in Chonburi, Thailand in December of 2001.

The new variety was first selected by the inventor, Thumrong Suphachadiwong, a citizen of Thailand, in November of 2006 in a research greenhouse belonging to the inventor in Chonburi, Thailand. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1312’, assessing stability of the unique characteristics of this variety.

Asexual reproduction of the new cultivar ‘SPCDW1312’ was first performed at a commercial laboratory belonging to the inventor in Chonburi, Thailand by tissue culture in June of 2007. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1312’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1312’. These characteristics in combination distinguish ‘SPCDW1312’ as a new and distinct Vanda cultivar:

-   -   1. Unique magenta flower color.     -   2. Large flowers     -   3. Thick petals     -   4. Tesslation pattern of petals.

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW1312’ are similar to the seed parent, Vanda ‘S243P’ in most horticultural characteristics. However the new variety, ‘SPCDW1312’ differs from ‘S243P’ in the following characteristics:

-   -   1. Stronger and better arranged flower spikes.     -   2. Flower is thicker.     -   3. Pink coloration is darker and flower has tessellation. Seed         parent flower color is lighter pink and without tessellation.

Plants of the new cultivar ‘SPCDW1312’ are similar to the pollen parent, Vanda ‘KMK96’ in most horticultural characteristics. However the new variety, ‘SPCDW1312’ differs from ‘KMK96’ in the following characteristics:

-   -   1. Brighter pink flower color than the pollen parent.     -   2. Larger flower size.     -   3. Larger plant size.

COMMERCIAL COMPARISON

‘SPCDW1312’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘SPCDDW1111’ in most horticultural characteristics. However the new variety, ‘SPCDW1312’ differs from ‘SPCDDW1111’ in the following characteristics:

-   -   1. The new variety has a magenta hued flower color, compared to         the purple flower of this comparator.     -   2. Different petal and sepal shape.     -   3. Weaker flower netting.     -   4. Petals are closer together.

‘SPCDW1312’ is similar in most horticultural characteristics to the unpatented commercial variety Vanda ‘Hot Magenta’ in most horticultural characteristics. However the new variety, ‘SPCDW1312’ differs from ‘Hot Magenta’ in the following characteristics:

-   -   1. Lighter flower color.     -   2. Flowers have wider dorsal sepals.     -   3. Larger lateral lobes.     -   4. Broader lips.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW1312’ grown in a commercial greenhouse in Honselersdijk, the Netherlands. The plant is 5½ to 6½ years old. Described plant not container-grown, but in a hanging basket without soil. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
